Vizio TV No Sound/Not Working 
Even though Vizio TVs are well-known for their picture quality and value, there isn’t a single smart television brand that doesn’t have its share of problems.
In fact, some users have reported that the sound on their Vizio TVs is not working.
If your Vizio TV volume isn’t working, we’ve got a few simple fixes for that, so you can listen to your favorite TV show while you watch it!
ℹ Vizio Sound Not Working? Try this quick fix first…
If your Vizio TV has no sound, you must reset it. Unplug your television from the wall and wait exactly 60 seconds. Next, reconnect your TV to the power source. This will perform a safe soft reset on your TV, allowing it to start right up and hear sound at the correct volume without any issues.
The above method is called a “soft reset” and will most likely cure the issue, but if it doesn’t don’t worry….because we have compiled a list of alternative ways to fix your Vizio TV no sound problem.
How to Troubleshoot Vizio TV No Sound Problem
Check the Remote Control (Have you Replaced the Batteries Recently?)
If you are unable to use the remote to increase and decrease the volume on your Vizio television, there may not be anything wrong with the television at all. Instead, the remote may be the source of the problem.
The remote control may have a problem.
It could be that the batteries have run out, or that the remote isn’t working properly.
A stuck button on the remote control can also be responsible for problems such as your Vizio TV turning on by itself.
If the TV still won’t change the volume after changing every battery and checking if the volume buttons are stuck, try this.
How Do I turn the Volume Up on My Vizio TV Without a Remote?
Try adjusting the volume of the television by pressing the Volume + and – buttons on the TV itself. Depending on the model of your Vizio TV, you’ll find the Volume + and – buttons on either the back of the unit or the bottom right side.
If the volume won’t adjust then you may have a bigger problem.
But fret not there are a few more tricks you can try to get your Vizio TV’s sound to work.
Check to See if Soundbar is Working Properly
If you are using a soundbar in your home theater setup, an easy fix is to make sure the soundbar is working properly.
With a soundbar installed, the television volume is routed through the soundbar speaker instead of the TV’s internal speaker.
Unplug your soundbar and disconnect all audio cables from both the soundbar and your Vizio TV.
Turn the volume up on your TV and if there is sound playing then the soundbar is the problem. Not your TV.
Check Current Channel Volume (Is it Working?)
It’s possible that the lack of sound on your Vizio TV is a result of the channel you are tuned in to, rather than the television itself.
Check a few different channels by changing the one you’re on with the remote and making sure that your TV still doesn’t make any sound.
If any channel starts playing sound, then the source of your problem lies with the channel broadcast or cable company and not your Vizio TV set.
Adjust Audio Input Settings
There is a button on the remote that allows you to change the audio source.
If you or someone else uses the remote and inadvertently hits the Input button the TV’s audio input can be accidentally changed.
You won’t be able to hear anything until you change it back, so be prepared.
In order to adjust the audio input settings on Vizio TV, below are the procedures to follow:
- Press the Input button on your TV remote
- If you have a soundbar connected to your TV, press it once and then pick Soundbar
- Or choose Default if you’re using the internal TV speakers
If the audio still isn’t playing it may be a problem with your audio cables.
Check Audio Cable Connections
Verify that all of the cables on your Vizio TV have been correctly plugged into each other.
If you have an HDTV or home theater receiver, make sure the audio wires (RCA or HDMI) are securely inserted into both the TV and audio source.
Interference might be caused by a cable that has come unplugged or is loose.
The sound from your TV may be muffled or muted as a result.
Check for any interference from any third-party devices as well, such as an audio receiver or soundbar.
Disable SRS TruVolume Feature
When using a Vizio TV’s TruVolume feature, your content’s volume is automatically adjusted based on what you’re watching.
External devices like gaming consoles and streaming devices like Chromecast and Roku might sometimes interfere with this feature’s ability to stream content.
Because of this, Vizio SRS TruVolume may not work well in conjunction with other equipment. It is possible to fix this issue by changing the preference setting from Prefer SRS to Off.
- Go to Audio Settings >> Advanced Audio
- Turn off Prefer SRS by selecting Off
Still, having sound problems? It may be time for a software update…
Update Your Vizio TV’s Software
If the software on your smart TV is out-of-of-date, you may encounter a variety of problems like loss of sound and even your Vizio TV not turning on.
Checking for and installing new Vizio TV OS updates can often be the solution to your problem.
It’s as simple as checking to see if your TV model has a firmware update available. Sometimes these updates are missed, but they are usually done automatically.
First, turn on your Vizio TV and press the Menu button on the remote. After that, select System from the drop-down menu.
Click on Check for Updates if it appears.
The Vizio TV Firmware Upgrade is now available for download.
Now, your TV will automatically start looking for updates.
If there are any software updates available for installation they will be done automatically by your TV.
Make sure to keep your Vizio TV up-to-date with the latest software by performing regular updates.
How to Factory Reset a Vizio TV
The factory reset option is recommended if either of the two steps above fixes your Vizio TV sound problem, but the problem returns at a later date.
If your Vizio TV doesn’t emit sound, it could be because of a software error. A factory reset of your television can resolve this issue.
- If you have access to a functioning remote control then try this method first (It’s the easiest):
- To access the menu, press the Menu button once the TV has been turned on (you may have briefly powered it up by disconnecting it or removing the remote batteries).
- Click the System option that should be present in the menu.
- Find Reset & Admin and Reset TV to Factory Defaults and then press Reset
Before performing a factory reset, the TV may request a code from the user. If it does, the default code is 0000, which is four zeros.
If you can’t find your remote or it doesn’t work then try performing a factory reset by using the buttons located on the Vizio TV itself.
- Find the Power (which is normally located on the side of the screen) and press it to turn the TV on
- Hold down the Volume and Source buttons
- A few seconds later, the TV will display a message that says Press and hold the input button for a few seconds
- About 10 seconds after pressing the Input button, let go of the button
- The TV will immediately reboot and enter factory reset mode. Rebooting and resetting your TV takes a few minutes.
Once the process is finished, your Vizio TV will return to the settings it had when it was purchased.

Contact Vizio Customer Support
Contacting customer support may be necessary if none of the above solutions work for you.
Vizio customer support is available via text message, internet live chat, and phone.
You can contact customer support at 1(844) 254-8087 if you want to speak with someone directly.
Customer service hours are 8:00 a.m. – 11:00 p.m. Central Standard Time, Monday through Friday
On the weekend the hours are 8:00 a.m. – 9:00 p.m. CST
You can also try out the Text Support or Live Agent Chat options if you prefer to commicate via typing.
While contacting support may resolve the issue, there may be other problems with your TV that you are unable to resolve on your own.
They can help you by working with you over the phone or by providing instructions on how to send in your TV for repair, if necessary.
Before contacting Vizio, verify that you have a warranty.
When you purchase a TV from Vizo, it comes with a standard one-year warranty.
If you purchased an extended warranty from a retailer like Walmart or Best Buy, verify what the terms and length of that third-party warranty entail.
Other Options (Nothing Has Fixed the Problem)
If you can’t find a solution to your Vizio TV no sound problem, and your TV is out of the warranty window then you really have two choices:
Purchase a New Vizio TV
If your Vizio TV is out of the warranty window, it may make more sense just to purchase a new television set altogether.
Smart TVs have never been so inexpensive, so you may be able to get a brand new TV that’s larger and has upgraded features for the same price (or less) as repairing your current model.
Repair your Vizio TV
You have the option to send your TV back to Vizio for repair, even if it isn’t covered under the initial warranty.
But a certified repair specialist in your area is most likely the best option.
In order to dismantle something, you must be extremely careful. There are a lot of fragile wire connections and high-powered circuits in the TV that might cause damage (or even electrocution) if you make the wrong move.
This is why we suggest sending your TV back to the factory for repair (even if the warranty has lapsed) or finding a certified TV repair specialist on your own to do the required repairs.
Unless you are highly skilled at electronics repair, we never recommend trying to replace internal parts (like a speaker) yourself!
